Eight-year-old Sophia Grace and her cousin Rosie, 5, became viral video stars earlier this month with an adorable rendition of Nicki Minaj's "Super Bass." But on Wednesday's Ellen DeGeneres Show, the English girls got the surprise of their lives when Minaj, 28, showed up for a surprise joint performance of their favorite song!

When Minaj came onto the stage, Sophia literally jumped for joy. The rapper gave her little fan a big hug, lifting her up and twirling her in front of the cheering audience.

"She blew me away!" Minaj told DeGeneres of Sophia. "Within five seconds of seeing [her] video, I was calling everyone! I was also receiving a billion emails. Everyone was like you have to see this little girl."

"Seriously, we are watching a journey that's about to be amazing," Minaj said of Sophia's talent. She also gave her some advice: "You are incredible. I just want you to stay in school. Music is beautiful, but stay in school, OK? Put your books first and singing second."

Then, much to Rosie and Sophia' delight, Minaj joined the girls for a joint performance of "Super Bass." Watch the adorable performance in the video above.
